It is a notably higher flow header, because in Europe it could not pass the regulations. You'll be lucky if you can find it super cheap. It should give a bit less comparing to a good aftermarket catted header. Reason is that it uses a normal cat. Current estimation is +5whp without a tune and everything else stock. Personally, I expect to gain a bit more because of the bigger throttle body. I don't have yet any change in the exhaust parts. Maybe a gain of 6-7whp, but of course I'll have to dyno the car. I'll post again when I have more information.
